AuthorTopic: 1DsMk11 locking up w/70-200 2.8IS (Read 2325 times)

I'm getting periodic lockup with my 1DsMk11 and 70-200 2.8 IS. I turn off the camera, remove and re-attach the lens and everything is ok again. Its happening a little more frequently lately. Has anyone here experienced this? Is there a fix?

There was a lengthy (25+ pages) discussion thread about 70-200 IS lockups on the "old" Rob Galbraith forums. I'm not sure if the archives are still available but from what I remember Canon replaced the IS unit. You might also want to search on DPReview.

Either way, I think it's a known issue with some 70-200s that are more than a couple years old. I had the same problem (it really only happens in IS mode), and sent the lens to Canon and they fixed the issue. Or I should say, I haven't experienced the issue since I sent it back -- that was a couple months back and I've taken a few hundred shots with it since.

If your lens is still under warranty, Canon will do the repair for "free". Here in Switzerland, I've never been offered any out-of-warranty repair. When questionned about the issue(s), Canon repair center only bothers to say that it's only web gossips.

It is a well known problem with an unclear fix.

For me it happened regularly on my 300D. But to my surprise (and happiness) it works perfectly on my 40D!
